Process of Preparing RDF Rod Making Machine from Domestic Refuse

1). Definition

1. RDF (Refuse-Derived Fuel) rod making machine is a device that processes recyclable solid waste (such as plastic, paper, wood, etc.) into solid fuel rods. It compresses loose garbage raw materials into a high density and a certain shape through a series of mechanical processing processes, making it easy to store, transport and burn.

2). Working principle

1. First, the raw materials that have been pre-treated (such as crushing, screening, etc.) are transported to the feed port of the rod making machine. Inside the rod making machine, there is a screw propeller or plunger device. When the raw materials enter the machine, the propeller will exert pressure on the raw materials, causing them to be compressed in the mold channel of the machine. As the pressure continues to increase, the raw materials are gradually compacted and squeezed out of the mold to form a rod-shaped fuel with a certain diameter and length. This process is similar to squeezing toothpaste, where the toothpaste is squeezed out of the outlet to form a strip after the toothpaste tube is squeezed.

3). Main components

1. Feeding device: used to stably transport the raw materials to the inside of the rod making machine. Its structural design should ensure that the raw materials can be fed evenly and continuously to avoid blockage or uneven feeding. For example, some feeding devices are equipped with agitators to prevent the raw materials from piling up at the feed port.

2. Compression device: This is one of the core components of the rod making machine. For example, the design of the screw shaft is critical for the screw propulsion compression device, and its parameters such as pitch and diameter will affect the compression effect of the raw materials. When the screw shaft rotates, it pushes the raw materials forward and gradually compresses them.

3. Forming mold: determines the shape and size of the fuel rod. Factors such as the aperture size, length, and smoothness of the inner wall of the mold have an important impact on the molding quality of the fuel rod. If the inner wall of the mold is not smooth enough, the fuel rod may have an uneven surface or break during the extrusion process.

4). Application field

1. Energy field: The fuel rods made by the RDF rod making machine can be used as an alternative fuel for industrial boilers, power plants, etc. It can partially replace traditional fossil fuels such as coal and reduce dependence on non-renewable energy. For example, some small biomass power plants use this fuel rod to generate electricity, burning it in a boiler to generate steam and drive a steam turbine to generate electricity.

2. Waste treatment field: It helps to reduce the amount of solid waste and recycle it. For some difficult-to-handle mixed waste, processing it into fuel rods through rod making machines can effectively reduce the amount of landfill. At the same time, it can also recover a certain amount of energy from the waste and improve the economic benefits of waste treatment.

5). RDF rod making machine has the following advantages:

1. Improve energy utilization: It can convert agricultural and forestry waste, domestic garbage and other materials that were originally difficult to effectively utilize into high calorific value fuel rods, realize resource recycling, improve the energy utilization efficiency of the entire society, and reduce dependence on traditional fossil energy.

2. Reduce pollutant emissions: When RDF fuel rods are burned, compared with traditional fuels such as coal, their sulfur content, ash content and other pollutant indicators are lower, which can effectively reduce the emission of pollutants such as sulfur dioxide and nitrogen oxides, reduce environmental pollution, and help improve air quality.

3. Strong material adaptability: It can handle various types of solid waste, such as wood chips, straw, rice husks, bark, plastic, paper, leather, clothing rags, etc. It has high compatibility with materials and can make full use of various waste resources.

4. Excellent fuel quality: The manufactured fuel rods have the characteristics of high density, high calorific value, stable combustion, etc., and the calorific value can generally reach 3200-5000 The kcal is even higher, and the quality is uniform and stable, which helps to improve the combustion efficiency and performs well in industrial boilers, power plants and other applications.

6). Production and operation

1. High production efficiency: With high production capacity, some large RDF rod making machines can produce several tons per hour, which can meet the needs of large-scale production and effectively improve the efficiency of waste treatment and energy production.

2. Low operating cost: The equipment structure is relatively simple and the maintenance cost is low. Its wearing parts are usually made of wear-resistant materials, with long service life and low replacement frequency, which reduces the operation and maintenance cost of the equipment. At the same time, the equipment has low energy consumption, which can reduce energy consumption costs.

3. High degree of automation: equipped with advanced control systems and automation devices, such as automatic feeding, automatic lubrication, automatic temperature control and other functions, it can achieve 24-hour fully automatic continuous operation, reduce manual intervention, improve production stability and reliability, and reduce labor costs.

4. Easy to store: The fuel rods have regular shapes, high density, small space, and are not easily affected by moisture or deterioration. They can be stored for a long time, which is conducive to coping with seasonal fluctuations in raw material supply and changes in market demand.

5. Easy to transport: Its regular shape and high density make it difficult to scatter or break during transportation. Conventional transportation tools and methods can be used for large-scale transportation, which reduces transportation costs and improves transportation efficiency.
